Title: Recording and reproducing method for optical information recording medium and recording and reproducing device
Inventor: NARUMI KENJI
IPC: G11B7/14
Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To record or reproduce information with sizes of optimum converged spots of respective optical disks without adding special optical elements or changeover mechanisms by changing modulation degrees of a high frequency superimposed current in accordance with various optical disks having different recording densities. SOLUTION: A discriminator 105 discriminates whether an optical disk 101 is the disk of a high density or a low density by reproducing information which are preliminarily recorded in the specific area of the optical disk 101. Then, a high frequency superimposed controller 106 changes the modulation degree of a high frequency current by a high frequency superposing device 107 with a control signal from a system controller 102 according to the discrimination result of the discriminator 105. This is, when an optical disk of the low recording density is to be recorded or reproduced, the modulation of the high frequency superimposed current of a semiconductor laser 110 is made larger than that in the time an optical disk of the high recording density is to be recorded or reproduced.

IPC: F24F13/15
Filed: 1986-02-17
Abstract: PURPOSE:To prevent the reduction of an air flow quantity from a outlet port by arranging a fin rotating shaft so that the rotating axis thereof has an inclination angle which is smaller than that of a outlet port with respect to the direction rectangularly intersecting with an air delivery. CONSTITUTION:When the operating portion 163 of an operating lever 160 is caused to slide up and down with respect to the air delivery from an air conditioner via a supply duct 101 and an opening and closing door 14 is rotated, it is possible to adjust the discharge quantity of air from a outlet port 11. Further, when an adjusting lever 170 is moved vertically and horizontally, horizontal fins 21 are rotated vertically and vertical fins 22 are rotated horizontally, the discharge direction (d) of an air from a outlet port 11 can be adjusted vertically and horizontally. A rotation axis (e) formed by being tied to a fin rotating shaft 23 of the horizontal fins 21 is directed more upward than the inclination direction of the outlet port 11, and the discharge direction (d) from the outlet port 11. Therefore, when the discharge direction (d) from the outlet port 11 is in the peripheral side of a delivery direction (f), the interval between the horizontal fins is not changed from the conventional one. When the discharge direction (d) is directed downward at the time of space heating and the like, the interval between horizontal fins 21 becomes wide, and it is possible to obtain a sufficient discharge quantity.
